Anyone remember this from a few pages ago ?

Q: What do paleotemperature reconstructions show about the temperature of the last 100 years?

A: Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th-century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions. Our primary conclusions are based on a comparison of the longer term paleotemperature changes from our reconstruction with the well-documented temperature changes that have occurred over the last century, as documented by the instrumental record. Although not part of our study, high-resolution paleoclimate data from the past ~130 years have been compiled from various geological archives, and confirm the general features of warming trend over this time interval (Anderson, D.M. et al., 2013, Geophysical Research Letters, v. 40, p. 189-193; Welcome to AGU Online Services).
A scientist has his take on it all.

The press release clearly explains that the paper (a) combines data from many sites around the world to create a "temperature reconstruction" which gives a "sense of the Earth's temperature history," and (b) "that history shows" a cooling over the past 5000 years, until the last 100 years when all of that cooling was reversed.
This scientist also goes as close as possible to suggest misconduct without actually doing so.

If this is climate "science" its pathetic.
